Houston, We Have a Phone Call!

"Alvin, this is the International Space Station Alpha, how do you hear us? Over."

These words started one of the farthest-reaching long-distance phone calls in history this afternoon when astronaut Sunita "Suni" Williams initiated a phone conversation with oceanographer Tim Shank. That may not sound remarkable - except that Suni was over 200 miles above Earth in the International Space Station while Tim was nearly two miles beneath the ocean's surface in the Alvin research submersible. Here’s Tim standing in front of Alvin prior to the dive.

The two explorers spent about 20 minutes discussing the similarities and differences between their work environments, what they each study, and what it is like to live in space and at sea. They also talked about swapping places one day, just to see what each other’s research environment is like – ah, just like a true explorer.
